Description
Hello,
Thank you for the great work!
For stage 4 (instruction tuning with HD data), the current code seems to resize/crop image to 224x224:
https://github.com/OpenGVLab/Ask-Anything/blob/main/video_chat2/scripts/videochat_mistral/config_7b_hd_stage4.py#L21
https://github.com/OpenGVLab/Ask-Anything/blob/main/video_chat2/dataset/__init__.py#L73
which means it's actually using 224x224 frames for training. Is that true? If so, what is this "HD" about? Or did I miss something?
Thank you!

Research direction
Start with video_chat2/scripts/videochat_mistral/config_7b_hd_stage4.py at line 21 and video_chat2/dataset/init.py at line 73, then trace the stage 4 image preprocessing path. Confirm whether training uses 224x224 frames and document the intended meaning of “HD,” or identify the specific discrepancy; done means a clear answer supported by the relevant code.
