Progress bar parameter instructions

During the task execution process, the progress parameters in the task output panel are as follows:

Abbreviation	Explanation
R	The number of frames currently rendered
C	The number of frames currently being VFI or processed
RPT	ReadProcessTime single-frame read processing time
WPT	WriteProcessTime single-frame render processing time
S	The most recently recognized transition
SC	The number of recognized transitions
TAT	TaskAcquireTime single VFI task acquisition time
PT	ProcessTime single VFI task processing time
QL	QueueLength VFI task queue length
SR	The number of frames currently being super-resolved
SRTAT	SuperResolutionTaskAquireTime single super-resolution task acquisition time
SRPT	SuperResolutionProcessTime single super-resolution task processing time
SRL	SuperResolutionQueueLength super-resolution task queue length

Special instructions for progress bar parameters

In version 6.x and above, the "Decode Pressure" and "Render Pressure" panels in the output status panel will show the current decoding and rendering pressure. When the decoding pressure and render pressure are both 0, it means that there is currently no performance bottleneck and it is in the best state. The greater the values of the decoding pressure and render pressure, the more serious the current bottleneck is. Note This value is inaccurate when using multiple VFI or super-resolution threads.
When only VFI without super-resolution, if the QL value remains below 10 for a long time, it indicates that the frame-extraction encounters a bottleneck. At this time, TAT>0.1. Please check whether the CPU usage is 100%. If so, please change the CPU software encoding render parameters (such as changing the render preset from slow to fast) or replace the CPU with more powerful single-core performance. If Fast Extraction is not enabled and the RPT value is large (>10s), please enable Fast Extraction to reduce the CPU load. When enabling the high-precision workflow and CPU render, if the CPU is not strong enough, QL=0 is a normal phenomenon.
When both super-resolution and VFI are performed, QL=0 and TAT>1 are normal phenomena. Try to ensure that SRL>0 and SRTAT to maximize the working efficiency of the graphics card, because SVFI performs super-resolution first and then VFI, for the same reason as above.
If the TAT (SRTAT) value is 0 and the QL (SRL) value is stable at a relatively high value, it means that the bottleneck of the working speed is mainly in the performance of the graphics card. This state can give full play to the performance of the graphics card, which is an ideal working situation.

Additional global settings

Note The current global settings correspond to version SVFI 6.15.9

This type of global settings is set in the global_advanced_settings.json file (referred to as GAS) in the software root directory and can be edited by opening it with a text editor. By default, this file needs to be created manually.

The following is an example of all configurations. The value of the key-value pair is the default value. You can directly copy the following content and edit it as your own GAS file.

When actually editing the json file, the value corresponding to the non-existent key uses the default value:

Key Name	Explanation
is_cudnn_enabled	Whether to enable cudnn acceleration.
trt_max_workspace_size	The maximum workspace size of TensorRT in bits. When using vspipe for upscaling, it is not effective and you need to manually change the workspace size of `vspipe.py`.
calib_sr_len	The calibration times of TensorRT when using int8 quantization.
is_cuda_graph_enabled	Whether to enable CUDA Graph acceleration for supported models.
is_torchscript_enabled	Whether to enable TorchScript mode for supported models.
is_cuda_loading_lazy	Whether TensorRT enables lazy loading mode, which can reduce video memory usage.
is_torch_trt_io32	Whether torch trt uses fp32 as the trt input and output. When enabled, it can significantly reduce the jagged edges caused by rife trt after forward deduplication.
is_rife_trtexec_prec_obey	Whether to use the precision constraints of RIFE trtexec. If enabled, add partial layer parameter range constraints to avoid possible image problems.
show_trt_debug	Whether to display TensorRT debug information.
debug_scdet	Whether to display debug information for scene detection.
fmnet_model	The FMNet model used, located in `models/restorer/FMNet/models`.
deep_deband_model	The DeepDeband model used, located in `models/restorer/DeepDeband/models`.
sisr_state_dict_key	The weight key of the custom SISR model used, applicable to ATD, SAFMN, SPAN, and Compact model structures.
use_minterpolate	Whether to use the `minterpolate` filter when reading videos with ffmpeg. Sometimes it can be enabled to correct the number of end frames.
pure_scene_len_threshold	Pure scene length threshold.
vfi_use_pad	Whether to use pad instead of interpolate for input resolution preprocessing in the frame interpolation process.
forw_dedup_use_pad	Whether to use pad instead of interpolate for input resolution preprocessing in forward deduplication.
forw_dedup_use_correction	Whether to use correction in forward deduplication.
