Understanding and Troubleshooting Video Editing Delays During Remote Desktop Sessions
Remote editing has become increasingly popular, offering flexibility and convenience. However, practitioners often encounter challenges such as video lag or delays when remotely accessing editing workstations. If you’re editing videos via remote desktop applications like AnyDesk and notice a lag in video playback, you’re not alone. This article explores potential causes—hardware, software, or internet connection issues—and offers practical insights to optimize your remote editing workflow.
Scenario Overview
In typical setups, an editing workstation (e.g., an iMac with high-end specs) is accessed remotely from a less powerful computer or laptop. For example, consider the following configurations:
- Remote Editing Computer (iMac 2020):
- Intel i9-10910 processor
- AMD Radeon 5700 XT 16GB GPU
- 128GB RAM at 2667MHz
- Wi-Fi connection
-
1Gbps internet package
-
Local Computer (e.g., Windows-based PC):
- NVIDIA GTX 1060 6GB GPU
- Ryzen 5 1500 CPU
- 16GB DDR4 RAM at 3000MHz
- Ethernet connection
-
70–90MB/s actual internet speed (approx. 560–720 Mbps)
-
Alternate Local Laptop:
- Ryzen 7 4800H CPU
- GTX 1660 Ti 6GB GPU
- 16GB RAM at 3200MHz
Remote access is achieved via AnyDesk, using DaVinci Resolve for video editing.
Observed Issue
When playing back videos during remote sessions, a consistent delay becomes apparent:
- Audio Playback: Nearly instantaneous, with audio starting immediately upon hitting play.
- Video Playback: Experiences roughly a 1-second delay before visual frames catch up with the audio.
- Progression: The video remains slightly behind as playback continues, especially noticeable during extended editing.
Despite this lag, editing remains manageable since the audio cues are reliable for making cuts in speech-based videos. However, problems arise when frame drops occur or footage synchronization becomes difficult, particularly when integrating secondary camera footage or lower-quality backup videos.
Potential Causes and Considerations
- Internet Connection Limitations:
- Despite high nominal speeds (e.g., 1Gbps), real-world performance can vary due to network congestion, Wi-Fi stability, or latency.
