Apple, the "it just works" company.

Why is it that I have to upload an FLV file to YouTube, and then re-download if from there as an MP4 file using a bookmarkelet, as the only way to effectively convert this FLV file to an MP4 file on my Mac while keeping the audio in sync with the video?

(the FLV wasn't compatible with iMovie, so I needed to convert it first)

It's sad that in 2013 I need to do this on an iMac to convert an FLV file to MP4 file without messing it up. And trust me, I tried everything imaginable before that. It saddens me. What should have taken 10 minutes took me fucking hours to get done.

Using which app?

I know. This is exactly what I'm saying. It's usually what Apple is good at, but in this specific area they've been useless for years. Heck, their very own HTML5 video player on their own website absolutely sucks.

I knew it wouldn't work.

This is the original FLV file. I've since deleted my conversion file.

I didn't get the file, someone else figured that out for me. But the file couldn't be that messed up considering uploading it to YouTube and redownloading it as MP4 without touching the video at all, perfectly trascoded it from FLV to MP4.

OK, enough time waste on this. **** Quicktime.

You don't have to export the whole 2 hours each time, just a segment, click on the time counter, switch it to frames and check that the number of frames in the output matches the frames in the source and that the audio length matches the video. Whatever is mismatched will let you track down where it's messing up.

Youtube it seems uses ffmpeg for at least some formats:

They might use software from Adobe for flv. VLC can transcode video direct to mp4 so that's another route to try. iSquint is another option:

Yes, yes, yes, but if I can upload to Youtube and download as an MP4 with perfect results - without thinking about anything - and there's no turn-key solution for doing it on my Mac, what method makes more sense? And why do I need to use Google because Apple can't provide an elegant solution? Like I said, I wasted enough time. This should be the least of my worries in 2013. I just sent Apple angry feedback on QuickTime and iMovie. I am furious!
