Marcel (Siff)'s Learning Log

Thank you for the tips and input. I tried some more things today after your input. Sadly no success.

Ableton is not very good with video it seems, it doesn’t have settings for it.
I went through troubleshooting guides and made several adjustments to the video conversion as suggested. No matter the software (even if setting the project framerate correctly in other editors like DaVinci Resolve) I can’t get the video to be the same length as the audio track.

I will try some different settings (4K/60 fps etc.) on the phone next time and see if they are better.

But by this point, I feel the iPhone just doesn’t record perfectly in time (maybe fluctuations because of the variable bitrate).

I’ve found some Reddit threads on similar problems, but none seem to offer a good solution, some say to just use other cameras or record the input over an interface connected to the phone. Which I don’t want to do as the audio will be no multitrack anymore, thus not really mixable after the fact anymore.

Can’t help with either Ableton or an iPhone.

@jkahn, perhaps you have more experience using both?

@DavidP I do use them both but suspect Marcel’s Ableton knowledge is a lot more than mine.

I don’t have iPhone audio sync issues these days but I did back when I used Adobe Premiere Elements.

I use Ableton for audio only, and export the WAV to import into resolve. I figure use an audio tool for audio & video tool for video.

Another thing I did at one point is to set my iPhone camera to “Most compatible” formats rather than “high efficiency”. That might have made a difference.

Thanks for chiming in some more.

Tried this and did some tests and no help.

Found a “solution” though:

After testing it with my Focusrite interface in the living room, there were no problems.
I have an older Mac I inherited in the recording room and tried it with the Behringer interface and it has no problems producing a sound file matching the video, even Resolve makes no fuss auto-aligning them.

So I highly assume my ethernet extension kit for USB may have introduced latency fluctuation or the Behringer drivers for Windows aren’t as good as the native Apple ones.

Guess I will be using the Mac for future recordings in this room. Luckily it is not as loud as my main pc.

Thank you for posting this ! It may explain the issue I was having, playing back the rideout video, as the default Project setting is 30 fps. I checked the MOV and MP4 files and they were 60 fps. So possibly not down to ASIO4ALL. Hey but doesn’t explain the ASIO issue that followed or that playback worked with the UMC Driver and later with FlexAsio. :thinking: MMmmmmm ?

What I could not find, was a setting in Preference to set/change a default fps value, so I guess I’ll just have to remember next time I use the helmet cam. :+1:

You can set it up to be the project default setting, but perhaps an issue if your studio webcam is different. Then you could set up a couple of project templates to accomodate different fps values.

Just checked the Hamburger “takes” and they’re are captured at 30 fps from the studio webcam. As the bike footage is rare these days maybe a setting change as and when.
Not sure if the Apexcam fps can be changed but the last rideout it was set to 1080 but can do 2700 and 4k but 60 fps makes more sense for an “action cam” recording. Memo to self :rofl:

Updated Routine:

As I still have a hard time memorising all notes on the fretboard and would like to advance a bit faster there, I added a little fretboard memorizing practice routine from another teacher.
Somebody made a nice app called Fretboard Forever which gives you a good tool for this method.

Good to see you’re still at it :smiley:
