# Apply renaming function to video previews (2025-10-23 15:52Z)

_**User (2025-10-23 15:52Z)**_

@UpdateSequences.bat let's apply the rename function to video previews; if a sequence includes a video file (always mp4), it also renames it according to the default flamenco script's naming convention: [job name]-[frame range] e.g. for a sequence in a folder called 06_Watering, with a sequence that begins at 06_Watering_000194.png to 06_Watering_000326.png, the preview-video is named 06_Watering-194-326.mp4. Rules:

1. Only check the mp4 for renaming if the sequence needs to be renamed to the folder's seq name
2. Rename the sequence first
3. Ensure the frames in the MP4 have NO pad. Sequences have six digits at all times (i.e. _000001, 000002, etc) but the mp4 has the simple frame range from the blendfile with no digit pad, e.g. 1-1234, and NOT 0001-1234 or 000001-001234.

I'll scan the PowerShell scripts to see how sequences are currently renamed and where to hook in the MP4 rename logic, then implement the changes in `UpdateSequences.ps1` so that mp4 previews are renamed after the sequence, using the no-pad frame range format.

<think><details><summary>Thought Process</summary>**Evaluating renaming process**

I need to check for any renames in Sync-SequenceFilenames related to the image sequence. The function currently returns counts, but it may be useful to enhance it to optionally rename an .mp4 if any renaming occurs or is needed. The rule is clear: check the .mp4 only if the sequence's name needs updating. I’ll also need to compute the frame range for accurate .mp4 naming and figure out how to identify the start and end frames.
**Defining frame range and renaming logic**

I'm considering using renamed sequence files to find the lowest and highest frame numbers after the rename process. The function seems capable of handling 6-digit numbers, and I’ll need to ensure we produce a range without padding. For example, the sequence "06_Watering_000194.png" to "06_Watering_000326.png" translates to "06_Watering-194-326.mp4." 

First, I’ll list image files and extract integers from the last six digits to compute the min and max. Then, if an .mp4 exists, I'll confirm its naming pattern and rename as necessary, only if renames occurred.
**Addressing renaming and edge cases**

For renaming, the rule is clear: start with the sequence first. I'm considering edge cases where there could be multiple .mp4 files. If that happens, I'll choose the most recent one or any that starts with the original job name, even though the implication is there should be zero or one. 

I’ll check for .mp4 files in the sequence folder, excluding any _archive folders. If I find more than one, I might skip or select the latest based on LastWriteTime. It's crucial to log actions and avoid collisions. If a target name exists at the same path, I’ll skip or remove it, taking care to only check .mp4 during renaming. But what if the folder's name matches and the mp4 is still incorrect?
**Implementing mp4 renaming logic**

The requirement states I should only check the .mp4 file if the sequence needs to be renamed to the folder's sequence name, so I’ll follow that closely. I plan to modify UpdateSequences.ps1 to extend Sync-SequenceFilenames, allowing for optional handling of .mp4 renames. It seems better to locate the .mp4 rename logic in the caller after checking the renameResult.  

I’ll create a new function, Rename-PreviewMp4. This will find image frames using the same allowed extensions, compute the min and max frame numbers, and build a target file name as "$SequenceName-$minFrame-$maxFrame.mp4". I’ll search for the .mp4 in the same folder without recursion, skipping the _archive directory.
**Implementing mp4 renaming updates**

I have to use -File -ErrorAction SilentlyContinue and ensure that if one .mp4 file is found, I rename it. If more than one is detected, I'll select the most recent based on LastWriteTime. I also want to keep StrictMode and logs in mind.

After checking $renameResult, if renaming occurred, I’ll call Rename-PreviewMp4. The function will collect image files while excluding _archive folders, compute frame ranges, and construct the target file name.

I’ll read .mp4 files and handle collisions appropriately, ensuring I log every action consistently. Additionally, I'll keep indentation of 4 spaces throughout the script. I’ll also implement a todo list before making these changes to keep everything organized.
**Finalizing mp4 renaming logic**

I’ll gather the number of .mp4 candidates found and set a `$checked` count based on those results. For searching images, I’ll avoid recursive search to ensure I only use images in the main folder, even if previous functions used recursion. This reduces the risk of getting incorrect frame ranges.

Once I collect frame numbers, I will use a regex to validate the sequence names. If I find no frames, I’ll return early. After finding .mp4 candidates, I’ll create a new target name and handle renaming as needed.

I’ll ensure to log actions consistently and wrap my calls to mp4 renaming in the condition verifying if a rename is necessary. Now, I’m ready to implement the code changes while keeping everything properly indented.</details></think>

---

I'll add a PowerShell function to rename preview MP4s based on the renamed image sequence's frame range, then call it only when the sequence files were actually renamed, ensuring the MP4 uses the no-pad frame range format. Now implementing the edits.

Tool use: **todo_write**

## Todo List

- [-] Add function to rename preview MP4 by image frame range (no pad)
- [ ] Invoke MP4 rename only when image sequence was renamed
- [ ] Log MP4 rename actions to _CURRENT\_UpdateSequences.log

---

<think><details><summary>Thought Process</summary>**Implementing rename logic**

I need to add rename logic in UpdateSequences.ps1. There's a function called Sync-SequenceFilenames that renames image files to a specific format. The user wants this logic applied to video previews too. If there’s an mp4 in the sequence, it needs to be renamed according to the flamenco script's convention, like using a job name and frame range. 

There are rules to follow: rename the sequence first, check the mp4 only if the sequence needs a new name, and handle frame padding correctly.
**Computing during renaming step**

I should compute the minimum and maximum digits for each file during the renaming process. We’ll collect these if any renaming occurs. I realize I should only rename the mp4 if the sequence was renamed to match the folder's name. If `renamed > 0`, that’s my cue. The mp4 should follow the format `${SequenceName}-${start}-${end}.mp4`, while ensuring that start and end are converted to unpadded integers. However, the current function, Sync-SequenceFilenames, only returns counts, not the required min/max.
**Adjusting frame tracking and renaming**

I think we need to adjust the function to return MinFrame and MaxFrame. I want to keep the linter style and rules intact, so I’ll modify Sync-SequenceFilenames to track the minimum and maximum digits across processed files. Even if some files are correctly named already and skipped, I want to capture the overall min and max for the frame range. 

I’ll scan all image files to extract 6-digit frames, and we should only rename the mp4 file if the renamedCount is greater than zero. I'll look for any mp4 in the sequence folder while renaming. There might be multiple mp4s, and I’ll handle them based on a certain pattern.
**Implementing mp4 renaming logic**

I’m clarifying the default naming convention for flamenco scripts, which is [job name]-[frame range]. I'll rename any mp4 that doesn't already match this format, but only if the sequence requires renaming. 

I need to ensure we handle name collisions similarly to images: if the target already exists, we skip it and log the event. The renaming of the sequence will occur first, so I’ll implement a new function, Rename-SequencePreviewMp4, which takes the sequence folder path, name, start frame, end frame, and log file as parameters. This function will loop through the mp4 files, skip if it matches the target name, compute a new path, and rename if there’s no collision.
**Implementing mp4 renaming and frame tracking**

I need to enhance the renaming process for mp4 files, ensuring I only rename one that doesn’t match the target name, ideally the first one found in the folder. To avoid confusion, I’ll pick only one mp4 to rename and will log any collisions similarly to image file renamings. 

Later, I plan to implement the function Rename-SequencePreviewMp4, which will enumerate mp4s and manage the renaming process while also updating Sync-SequenceFilenames to calculate min and max values for the digits extracted. I’ll ensure minimal impact on the original structure while keeping the code concise and following proper formatting guidelines. This way, I maintain all necessary details in a clean and well-organized manner.
**Finalizing frame tracking and logging**

I’m setting up my initial variables early to track minimum and maximum frames. After detecting digits, I'll ensure they're updated correctly and add these to the returned object without conflicting with existing property names like 'Renamed' and 'Errors'.

In the call site, after computing $renameResult from the foreach loop, I'll call Rename-SequencePreviewMp4 if certain conditions are met. I plan to introduce new counters for mp4 files and print concise logs for clarity, keeping changes minimal. Detailed logging within the function will maintain a style similar to Sync-SequenceFilenames while ensuring to respect edge cases where no renames occur. All this while maintaining proper indentation and avoiding unnecessary comments!</details></think>

I'll implement a new PowerShell function to rename preview MP4s based on the image sequence frame range, extend the existing rename function to track min/max frame numbers, and call the MP4 renaming only when image files were actually renamed.

<think><details><summary>Thought Process</summary>**Fixing PowerShell Lints**

I need to fix some linter issues in my PowerShell code. The rule states that `$null` should be on the left side of equality comparisons, and the specific flag is at line 179. So, I'll change `-ne $null` to `$null -ne $renameResult.MinFrame`. Then I also need to modify the condition to make sure both `MinFrame` and `MaxFrame` aren't null. Additionally, I need to preserve indentation and follow the user rule regarding script generation, as they requested specific modifications without generating a full script.
**Checking MP4 Naming Conditions**

I need to ensure that we only check the MP4 for renaming if the sequence requires it to match the folder's sequence name. My condition checks whether files were renamed, which is great, but I also have to consider if the sequence is already correct; then, we can skip checking the MP4. If the MP4 is incorrect, we still need to follow the rules and focus on renaming the sequence first. I also need to ensure that the frames in the MP4 don’t have leading zeros!
**Determining Rename Sequence Logic**

I need to decide whether calculations occur before or after renaming in the Sync-SequenceFilenames function. I’m iterating through files and parsing digits while keeping track of mismatches. It's fine to process only those matching, as I can still compute the min and max even if renaming collides. They want to use frame ranges from the blend file, corresponding to the sequence frames present. 

I need to consider edge cases with multiple MP4s in a folder and handle collisions by skipping renames if the destination exists.
**Updating Task Progress**

I created console prints and log entries for the MP4 functionality and set up a todo list. I marked the first task as in progress. After applying the patch, I finished the function to add tasks. Now, I need to update the todos: I should mark the MP4 function, the MP4 log, and the logging call as completed since they were all done. However, first, I need to fix the lints regarding `$null` comparisons before I wrap things up!</details></think>

## Todo List

- [x] Add function to rename preview MP4 by image frame range (no pad)
- [x] Invoke MP4 rename only when image sequence was renamed
- [x] Log MP4 rename actions to _CURRENT\_UpdateSequences.log

---

I added MP4 preview renaming tied to the sequence rename, using the no-pad frame range.

- Edits in `UpdateSequences.ps1`:
  - Extended `Sync-SequenceFilenames` to gather `MinFrame`, `MaxFrame`, and `FrameCount` from six-digit sequence numbers.
  - New `Rename-SequencePreviewMp4` function: renames a `.mp4` in the sequence folder to `[SequenceName]-[start]-[end].mp4` with no zero padding, ensures collisions are handled, and logs actions.
  - Only invokes MP4 rename when image files were actually renamed in that folder and a valid frame range was detected.
  - Summary now includes MP4 rename counts.

- Behavior matches your rules:
  - Renames MP4 only if the sequence needed and received renaming.
  - Sequence is renamed first; MP4 follows using the computed min/max frames.
  - MP4 frame range uses no pad (e.g., `06_Watering-194-326.mp4`).

You can run it via `UpdateSequences.bat` as before.

- Files changed: `UpdateSequences.ps1`
- Important snippet showing the guard and rename call:
```150:187:A:\1 Amazon_Active_Projects\3 ProjectStructure\UpdateSequences.ps1
            $renameResult = Sync-SequenceFilenames -SequenceFolderPath $s.FullName -SequenceName $s.Name -LogFile $logFile
            ...
            if ($renameResult.Renamed -gt 0 -and $renameResult.FrameCount -gt 0 -and $null -ne $renameResult.MinFrame -and $null -ne $renameResult.MaxFrame) {
                $mp4Result = Rename-SequencePreviewMp4 -SequenceFolderPath $s.FullName -SequenceName $s.Name -StartFrame $renameResult.MinFrame -EndFrame $renameResult.MaxFrame -LogFile $logFile
                ...
            }
```

- Quick note: the MP4 finder is simple (first `.mp4` in the folder). If you want it to target a specific naming pattern or recurse, say so and I’ll adjust.

<think><details><summary>Thought Process</summary>**Evaluating PowerShell error**

I'm encountering an error when running UpdateSequences.bat that says, "ERROR: The term 'if' is not recognized as the name of a cmdlet." This suggests PowerShell is struggling to parse the script due to potentially incorrect usage of 'if'. It seems like the script may have an invalid syntax, as using 'if' inline isn't supported in versions before PowerShell 7, and this happens often when there's confusion with previous lines. I'll need to double-check the syntax.
**Fixing code expression issues**

In the code, using an expression like `(if ...)` is causing the error: "The term 'if' is not recognized as the name of a cmdlet." This occurs because PowerShell is interpreting 'if' incorrectly. To resolve this, I need to modify the creation of the PSCustomObject by calculating variables first. For example, I can set `$min` and `$max` before the return statement. I'll need to check the script carefully to ensure there are no similar issues elsewhere. Let's get into the file to make those adjustments!</details></think>

---

I saw the script error stems from using an inline if-expression inside the hashtable for the return object, which isn't valid in PowerShell 5. I'll fix `UpdateSequences.ps1` by assigning `MinFrame/MaxFrame` to variables before constructing the object.

<think><details><summary>Thought Process</summary>**Fixing PowerShell syntax error**

I need to address the error about the inline 'if' being unrecognized in the cmdlet. This shows invalid syntax in the hashtable on lines 91-92, where I mistakenly used "(if (condition) { ... } else { ... })". PowerShell doesn't support inline 'if' in expression context; instead, it uses standard if/else statements for older versions. I also fixed the null comparisons earlier, but now I need to adjust the code to compute properties using prior variables, editing UpdateSequences.ps1 while keeping the indentation consistent.
**Updating PowerShell code**

I need to replace the return block by calculating $minOut and $maxOut before constructing the PSCustomObject. I'll set those variables to $null initially, and if $frameCount is greater than 0, I'll assign them their respective values. To maintain code style, I'll make these changes right before the return statement while ensuring there are no other inline if statements in the code. I'll use apply_patch for this, then run read_lints again afterward. I’ll consider updating the todo list, although it might not be necessary since it’s a minor fix.
**Revising developer flow**

In the developer flow, I need to reconcile the TODO list via todo_write before making any new file or code edits. That means marking completed tasks and setting the next ones to in_progress. Since we've completed tasks, I could skip this step because I'm making an additional fix. I'll add a micro status update before calling tools. I’ll say something like, "I'll fix the invalid inline if usage by assigning variables first, then update the file, apply the patch, read lints, and produce a final summary."
**Preparing patch for UpdateSequences.ps1**

I should confirm that we previously changed the comparison to null to use $null -ne var in UpdateSequences.ps1, which is good. Now, I'll create a patch to replace lines 86-94 so that we compute $minOut and $maxOut. I need to ensure I have the exact context lines for apply_patch, which includes lines 86-94. I’ll replace the inline if statements with a standard if structure for better clarity. After I apply the patch, I’ll read the lints and then consider updating the TODO list.
**Incorporating micro updates**

I think it’s a good idea to add quick micro update lines to adhere to our status update specifications. If a turn contains any tool calls, we should include at least one micro-update near the top before those calls. I’ll make sure to preserve the indentation at 4 spaces since the file uses that format. Once I’ve added the updates, I’ll go ahead and run apply_patch to implement the changes.</details></think>

I’m going to fix the invalid inline if-expression in `UpdateSequences.ps1` by assigning `MinFrame` and `MaxFrame` to temporary variables before creating the return object, ensuring PowerShell 5 compatibility.

I fixed the PowerShell 5 compatibility issue by removing the inline if-expression in the return object and assigning `MinFrame`/`MaxFrame` to variables first. You should now be able to run `UpdateSequences.bat` without the “if is not recognized” error.

- Key edit in `UpdateSequences.ps1`:
```86:96:A:\1 Amazon_Active_Projects\3 ProjectStructure\UpdateSequences.ps1
    $minOut = $null
    $maxOut = $null
    if ($frameCount -gt 0) {
        $minOut = $minFrame
        $maxOut = $maxFrame
    }
    return [pscustomobject]@{
        Renamed    = $renamed
        Collisions = $collisions
        Errors     = $errors
        Checked    = $checked
        MinFrame   = $minOut
        MaxFrame   = $maxOut
        FrameCount = $frameCount
    }
```

Let me know if you want me to target only certain `.mp4` naming patterns or search subfolders for previews.
