Handbrake: Quicktime "trim" start/end not respected

[verde-io]

Description of the problem

I am using the built-in macOS screen capture function to record some websites I've worked on. I trim the final videos to the required start/end position before saving them as MOVs.

I then use Handbrake to convert them to MP4s, but the trim start/end points I've set seem to be ignored. Is this a limitation or a bug? Thanks.

HandBrake version (e.g., 1.0.0)

1.20

Operating system and version (e.g., Ubuntu 18.04 LTS, macOS 10.14 Mojave, Windows 10 1809)

macOS 10.14.2 Mojave

Error message text or screenshot

Please provide any error messages or screenshots that may help.

Please provide an input sample.

[verde-io]

@cehoyos You can download a sample here https://www.dropbox.com/s/0t7j18x97r36qrd/anna-rosa-intro.mov?dl=0

Thanks!

[verde-io]

As another info, if instead of doing just a Save in Quicktime I do an Export and then put the mov through Handbrake, the trim is respected, as expected.

[galad87]

Your sample seems to work. Do you have another to reproduce the issue?
If you export in QuickTime it will reencode it, and it won't need edit lists anymore.

[sr55]

We've not heard back in a while so we are closing this issue out. If you can provide the requested details or feedback we can re-open this issue.

Thanks

[butaca]

I'm having the same issue. It is super easy to reproduce in Mojave. Just do some screen recording, trim it before saving (clicking the preview at the bottom right of the the screen) and then encode it with HandBrake. In fact I use this all the time and the workaround is exporting it from Quicktime before sending it to HandBrake.

HandBrake Version 1.2.2 (2019022300)
macOS Mojave 10.14.4

[cehoyos]

Please provide an input sample.

[butaca]

Thanks for taking a look into this. Here you have the original capture (01_original.mov) and the encoded video with HandBrake (02_encoded.mp4): https://www.dropbox.com/sh/9neb7xae0uzahv2/AAAVNb9ewR_fZDTsZrI91CEea?dl=0

The encoded video starts earlier than the original.

[butaca]

@cehoyos I see the issue is still closed. Is my sample useful? Do you need something else?

[cehoyos]

Afaict, the sample you uploaded - 01_original.mov - contains an edit list. If the edit list is ignored, a very short subtitled scene is shown ("...You'll be one of them, sooner or later...") before a jump cut, the edit list requires that playback starts right after the jump cut (no subtitles shown).

[butaca]

Thanks for your response. I found out that some video players respect the edit list and other don't. As a user, I would expect Handbrake to follow the edits.

[jstebbins]

Should be fixed in the next nightly build

[bradleysepos]

Nice one, thanks @cehoyos and @jstebbins.
