Prores shouldn’t have anything to do with it.
In the frame controls did you select ‘Set Duration to 100% of Source?’
Also, roughly how far off is the sync? If you had to guess, does it seem more like the difference between 24 and 30, or 23.98 vs 24?

I know of two ways around this.
Personally, I don’t bother to link the sync audio, and just keep a sync/assembly sequence with all my synced media. I don’t mind the extra work to extend clips, etc. in the name of keeping it simple.
The other option is to select your synced/linked clips and select ‘Make Independent Clip.’ If you drag these to a bin in the browser window it will create new master clips.

It sounds like it removed frames without changing the frame rate. What process did you use to inverse telecine?

Check where your auto-save vault is. It’s possible that it was saving to drive that is no longer mounted.

Chances are your mp4 files are from a camera that records in the h.264 codec. H.264 is an extremely compressed “delivery” format, compared to a less compressed “editing” codec like prores.
In other words, your mp4 files use a much more complex compression algorithm than FCP is capable of editing live. At first it probably worked, but because of the complex compression, it requires FCP to process way more information per cut, and will eventual start causing out of memory warnings.
It’s the same reason that mp3 files always need to be rendered, but more intense cause it’s video.

I honestly don’t know how the slate information could even exist if it was removed and exported as a self contained movie.
As a solution, I would try removing the slate and exporting the video as a separate step from the h264 encoding. A codec like prores will only use i-frames, and therefore there should be no chance of the video containing information from previously existing frames.
Also, you might want to try creating an mp4 instead of an mov, since that is the format that Youtube uses for higher quality video. With MPEG Streamclip, you will have the same codec flexibility that you have with mov in compressor. I’m not sure if that would help, since Youtube will probably re-compress it anyway.
Does anyone know if there is a way to override the Youtube compression?

Interesting problem. Is it possible that the still is in the meta data and not the cut itself?
If the entire slate is appearing in the uploaded video, then my assumption is that Youtube is not updating properly, and is using an older upload. I’ve seen this type of thing happen before.

If you are dealing with HD than you should avoid the term NTSC completely.
If you are using compressor to create a ProRes 4444 file, than that is the preset you should use. Also, always double check the geometry tab, and make sure it is 1920×1080.

Sounds like you are already in Blu-ray specs.
Be careful when using terms like NTSC and PAL, as they refer to much more than American vs. European video specs. They are very specific terms that refer to SD footage for broadcast. Good luck.

For HDSLR transcodes I always use MPEG Streamclip. It’s free, fast, and maintains the original file name.
Here’s a good way to do it. Create an identical folder structure to the one you are currently using, but use a different name for the root folder. Create a batch in MPEG Streamclip, and select the h264 footage (one folder at a time, choosing the new identical folders as the destination). Start batch and wait.
When it is done, quit out of FCP, change the name of the root folder for the new transcoded footage to the name that the h264 footage folder uses.
Re-open FCP and the files will be re-linked automatically. Done.
You’ll probably have to change your sequence settings, but shouldn’t need to render anything (unless you used effects).
