Recording Missing Frames
-
I have a standard plus asccount. Two players, both on Windows. Recording video for a complete session ~ 60 minutes. I am using Blue Yeti mic for both record and playback. Not sure about other party’s equipment. Package of recordings includes a mix mp4, mix wav, and 3 single track files: 1-mkf, 2-scott, and 3-scott. I (mkf) was set for mono. 1_mkf and 3_scott were the same length. 2_scott was a different length. 3_scott (the one with the matching length) had no sound. 2_scott did have sound.
1_mkf seemed to have periodic silent frames, as though it was interleaving sound from channel 1 with silence from channel 2. mkf video and scott video were wildly out of sync.This does not always happen. For the example above, the problem happened from start of session. Last time it happened it started mid-way through session. We have also had a few sessions with successful recordings.
Also, Scott is using a free account. He sometimes gets disconnected about the 45-minute mark, even though I have standard-plus. excerpt attached

Hi Marylin,
Thanks so much for the mp3 with the dropouts. Could you see whether any of the following help?
- Plug in your computer’s power cable. Go to Start > Settings > System > Power & battery and make sure the Power mode for using the PC while plugged in is High Performance.
- Quit other apps, especially apps that use audio.
- Go to Start > Settings > System > Sound. Click More Sound Settings (Windows 11) or Sound Control Panel (Windows 10). Click Recording. Double-click your Yeti mic’s listing. Click Advanced, and set the Default Format to 16 bit, 48000 Hz (DVD Quality).
- Try a different mic.
- Go to FarPlay’s Preferences > General Options and change the Audio Buffer Size to 480 (10 ms).
Indeed, Scott shouldn’t get disconnected at 45 minutes from sessions you start from a computer authorized using your subscription. Did Scott happen to create the sessions where he got disconnected around 45 minutes? Sessions created by free users do time out at 45 minutes, even if the other participant is a subscriber.
Are mkf and scott video out of sync in the gallery mp4? I’d be happy to look at your mp4s if you’d like to upload them to a folder I shared with you separately through email. When someone leaves and rejoins partway through a session, you’ll have two recordings from them. In your example, 2-scott contains Scott’s audio/video until he first disconnected while 3-scott contains black video and silent audio before Scott rejoined followed by his audio/video after he rejoined. If you start playing the three recordings at the same time (in a video-editing app), they should be in sync.
Thank you,
David LiaoDear Friends,
I checked with our CTO, Anton. In very rare cases, sync may be off in recordings when using Windows’s built-in audio drivers (using a headset or Yeti mic, for example, plugged into your PC uses these drivers). If this problem happens to you, see the suggestions below.
- Go to Preferences > General Options and raise the Audio Buffer Size (might need to go as high as 480, depending on the audio device).
- Alternatively, use an audio interface (examples: Focusrite Scarlett or iRig Stream Mic USB) and its manufacturer-supplied ASIO drivers, like Marilyn did when she switched from her Yeti mic to her PreSonus audio interface. Using manufacturer-supplied ASIO drivers offers the additional benefit of letting you get lower latency than with Windows’s built-in audio drivers.
Thank you,
David LiaoDear Marilyn,
Glad you were able to record to your C: drive. Thank you for the audio samples. The distortion in the recordings sounds to me like a performance issue with the audio device on Scott’s end. Please ask him to try the following.
- If you’re on a Windows PC with an audio device that doesn’t have manufacturer-supplied ASIO drivers (examples: headset plugged into PC or Yeti mic), go to FarPlay’s Preferences > General Options and choose a higher Audio Buffer Size. When using audio drivers that Windows supplies, some audio devices need a high Audio Buffer Size of 480 to work stably. If raising the Audio Buffer Size enough to prevent distortion makes the latency too high, see the next suggestion.
- If you’re on a Windows PC and can get an audio interface with manufacturer-supplied ASIO drivers (examples: iRig Stream Mic USB and Focusrite Scarlett), set it up with FarPlay following the instructions in “Step One: Get Ready” in the version of our QuickStart guide customized for Windows PCs with external audio interfaces. Using an audio device with manufacturer-supplied ASIO drivers typically gives more stable audio and substantially lower latency than using audio drivers provided by Windows.
Interested in how it goes,
David Liao
