Do you like these release announcements or shall I keep it silent?

v0.5.2 out

Bug fixes

  • Rig tilt/roll save corruption fixed (degrees/radians mismatch). Could cause the export to be upside down.

  • Export no longer hangs when using start time with GPU decode

  • Multi-file segments now report correct total duration

  • Clip length capped to the shorter camera to prevent EOF issues

  • Windows export path false-positive read-only check removed

  • “Finalizing” status no longer appears at export start. More accurate messages.

  • Sync offset crash on out-of-range values prevented

  • FFmpeg console windows hidden during calibration on Windows

  • ORT log spam filtered

Quality API

  • --crf replaced by --quality-value (0-100, higher = better)

  • Consistent bitrate output across NVENC, VideoToolbox, and other encoders

GUI

  • Sync offset: text input with Apply button (was a laggy slider)

  • Export errors shown inline in the export dialog

  • [+] button appends segments instead of replacing

  • [X] button works for single files

AI detection debugging

  • New scripts/visualize_detections.py for inspecting what the AI sees

  • PannerDebug event showing cluster, ball, and FOV decisions per frame

Packaging

  • DirectML.dll bundled in Windows release (fixes #304)

  • YOLO 640 model available for faster inference on integrated GPUs. Highly recommended, shouldn’t lose too much accuracy.

How to visualize AI detections (CLI stitch only, will be supported in GUI in v0.5.3)

# 1. Export with events
reco stitch left.mp4 right.mp4 -c cal.json -o output.mp4 \
    --model yolo26n.onnx --tracking field --events events.jsonl

# 2. Render annotated video (both cameras stacked, with ROI overlay)
python scripts/visualize_detections.py export events.jsonl left.mp4 right.mp4 \
    -c cal.json -o annotated.mp4

# 3. Or browse frame by frame (arrow keys to step, q to quit)
python scripts/visualize_detections.py browse events.jsonl left.mp4 right.mp4 \
    -c cal.json

Requires opencv-python (pip install opencv-python).

I like these realease announcements. Great change the sync offset, in my case I had to put it in 0 and with slider it was a little bit difficult.

Thank you!

I tried to export this:

What is adv_inception_v3_Opset16.onnx ?

Does it work with the provided yolo.onnx or yolo_640.onnx models?

I replaced it with yolo.onnx and retried it. it seems to be exporting, but shows no progress. Bottom of GUI just says: Exporting: opening encoder and decoders and hasnt changed in 30 minutes

Any suggestions why it just seems to hang on processing?

I’ll work on it tomorrow. Let’s move the discussion to private chat.

So finally managed to get a stitch together of a game of touch rugby. Due to me, conditions and equipment, really poor quality. AI doesn’t stand a chance (it seems to vaguely look around the half of the pitch with no players on it…).

Would it be possible to setup a manual tracking recording? So record my personal point of focus whilst playing the video as I track along with it? Maybe horizontal only to make it smoother (or as an option)? Or perhaps even as a combination thing, so I can select which times to override the AI and instead track what I’m on? That way as I provide better footage it can track more easily, AI can do most the work, but then I can still override. Rugby has a disadvantage over football in that the ball can be out of sight for long periods, and a cluster of players isn’t always necessarily the right place to look (or vaguely looking at open field… but again, that’s probably on me!).

EDIT - Using the “Field” option definitely helps, it tracked the group of players much better, but still off, since the weight of players is basically spread, despite the action being on the far side.

EDIT EDIT - This could also be useful in terms of clipping for coaching etc, where the main play/ball is, isn’t always what you want to be pointing out to players. Sometimes it’s positioning in the backfield etc.

Were you able to use “ROI” to select the field and have the AI only consider players that are there?

If you are curious you could try the other pre-release I have published. v0.5.3-beta.1 Release v0.5.3-beta.1 · reco-project/video-stitcher · GitHub

It should have better tracking.

Is the stitch seamless or is it not perfect? Show us a screenshot if possible!

Once again sorry for not having clearer instructions. It will become simpler and clearer. In the meantime, have a look at QUICKSTART.md video-stitcher/QUICKSTART.md at main · reco-project/video-stitcher · GitHub

Trying the 5.3 beta. Seam isn’t perfect, but it’s well timed with playing with the offset. I can’t get the Autocalibrate to work well, so I’m relying on an older calibration not from the pitch. When I try from these videos, it completely squashes the left side, bringing the posts right up close. I’m guessing if I’d put a cone in between the blue and yellow (like a red one), it would have given it a nice point to lock onto. Though just now it worked, but still worse than the other older calibration.

Tracking field definitely helps. Unfortunately my clips aren’t long, the exposure was different (so used editing to improve brightness of one), and one of the phones decided to revert back to 1080p recording instead of 4k, which took me far too long to realise (lots of wasted time failing to get any image up, obviously exposure reset too etc). So had to upscale it with an online AI. I’ll try and find a better pair of clips to work with (after realising all the things I needed to correct I just worked with one pair of clips).

Please do not apologise for my ignorance and poor recordings!

This is a picture of the seam at it’s best (again, this was me holding the phone holder, so not stable at all. The tripod has just arrived, but need to do some adaptations to get it to actually hold the phone holder.

Going to keep on playing around, hopefully with a better clip for better results.

EDIT - At the moment, the quality just isn’t there for the ball tracking I believe. It was evening when recorded, and unstable due to me. I’ll try and get hold of another better quality phone so I can try and get a better result in a few weeks time. I can certainly see the potential. And with a lens calibration (lg g6 doesn’t have one) I suspect it’ll go even smoother.

As you can see the pitch, in the horizon, is slightly curved. This indicates you are not using a perfect lens profile and is the most probable cause as to why the seam isn’t perfect and to why the Autocalibrate fails. This page describes how you can film a video that will allow you to create your custom lens profile: Lens Calibration | Gyroflow documentation
That Gyroflow app has a built in Lens Profile builder that is compatible with Reco. Otherwise you can just send me the video and I will try to calibrate it for you.

The resolutions and details seem fine, but the AI will have a very hard time if the rig is moving. Also, the app assumes that the cameras are fixed between one another. So if you were holding each in a hand, it will miserably fail.

Did you try lookahead? It should help.

I haven’t had time to test when input resolutions differ. On paper it should work but I did not really experiment it. Did it fail completely for you, until you resized it?

Thank you for all your efforts and testing, it helps a lot. Sorry for late response.
And for tripod, use some tape :smiley: I always end up using that lol.

Hello @DenSoccer,

It’s been a while! Are you still encountering the issues above? v0.5.3 shipped many new fixes targetting export hangs.

Maybe you could try again? And if you ever get new bugs, please consider using the Report button in the Desktop App, as it attaches the logs and allows me to debug better.

Thanks!!
