You are using one of my experimental builds for the 7D. Isn't that proof that there is still some development going on for this camera? Also note that when any branch gets updated, the 7D will probably also be updated.

Thanks so much for sharing your 7D builds! In the FWIW dept. here are some testing findings (...2019Mar22.7D203 build, global draw off):

I can't get a clean "stop record" (in crop rec mode, any res). The record icon stays on the screen and I have to exit live view, reboot camera. But the files are good. 2496x1198 @24fps 10 bit no problem.

In non-crop mode press record locks camera. Have to R&R battery to clear.

Cannot get mlv_play to load at boot time. (granted it is so slow playing back files this size, but it has use in verifying framing in crop rec mode)

In debug I noticed that two memory patches appear when in live view. From what I read on other camera model threads this appears to be normal?

For now I'll spend more time with the Mar02, will report anything I find, but it seemed pretty stable the last couple of days.

best regards

This topic went through a cleanup and some off topic items were split off so I wanted to make sure 7D users get the message:

I made a new build that supports 10bit/12bit raw video and posted it on my downloads page. This works with both mlv_rec and mlv_lite and seems to be more stable than previous builds. In order to use mlv_play with reduced bit files you'll also need to load the raw_twk module.

Note that development is continuing on the 2.0.3 firmware. I also have an experimental 2.0.6 branch going on but I couldn't figure out how to get the Master processor to give up its secrets so it is only a partial firmware update. Any help with dumping the firmware for the Master would be greatly appreciated. Note that this would also help with other dual processor cameras like the 5DS, 5DS R, 5D4 and of course the 7D2.

Thanks! I've loaded it and will let you know if I find issues, but initial testing was very smooth and uneventful.

best regards

I got a report that the 5x zoom mode is off center. Not surprising, it is probably affecting other branches too. There was a similar issue a while back on the 60D. Read through the Raw Video framing is off when using 60D's 'Movie Crop Mode'. Help! topic to see how that was resolved.

There's also some reports of corrupted frames. I have not been able to reproduce the issue but I haven't tested extensively. Danne and Levas have been working on some solutions. It would be great to get the Digic 4 cameras onto their bleeding edge branches to see if these fixes are also working on these older cameras.

Very first clip I used with the new build.

99% great, basically.

ONE bad frame, BARELY, out of what I did so far.

Did the bad frame happen with mlv_rec or mlv_lite?

There are some experiments getting Digic 4 cameras working on the newer crop_rec branches but it only works with mlv_rec. Though don't expect the crop_rec module working on the 7D camera anytime soon.

I don't personally care for crop_rec.

All I used was mlv_rec.

This happened with 'card backup' setting enabled.

I disabled it after.

Ok--so the bad frame happened with mlv_rec. Good to know.

Have you tried mlv_lite on my experimental build? Advantage is that it should be using less processing power so possibly fewer corrupt frames. Disadvantage is that it doesn't record audio. (It is an early implementation of mlv_lite on this branch.)

Normally, no. But I don't find myself needing audio, most of the time. So I suppose I could use it for the better!
